Stainless Steel / 302/304/304-L P-BAR

Plate bar form of our 302/304/304-L. The material is an austenitic chromium-nickel stainless steel that is annealed (Condition A). These products have been used typically for parts requiring corrosion and heat resistance up to 800 F (427 C), especially when such parts are welded during fabrication, and for parts requiring oxidation resistance up to 1500 F (816 C), but usage is not limited to such applications. This combination of properties is the reason for the extensive use of these alloys, which represent nearly one half of the total U.S. stainless steel production.
